:APPARATUS FOR MAIfiING ICE.

To all whom it may concern: I 3

Be it known that I, ZENAS U. Donor, a

citizen of the United States, residing at New York, in the county andState of New York,

have invented certain new, and useful Improvements in Apparatus for'Making Ice,

. that the cans-"may be readily and conveniently placed in position inthe freezing tank. The novel features of the invention will be apparentfrom the following descriptiontaken in connection with the accompanyinga reduced scale.

drawings-in which:

Figure l is a fragmentary longitudinal section of a freezing tank withone of the ice cans shown in section. Fig. 2 is a trans verse sectionofthe tank shown in Fig. 1, on Fig. 3 is a fragmentary longitudinalsection of one of the ice cans and a portion of the bottom of thefreezingfreezing tank which may be of any suitable construction and hasarranged on the bottom.

thereofa series of conduits 11,- on which rest the ice cans 12. Theconduits 11 are supplied with brine from a suitable header 13. At thetop of the tank are arranged the intersecting beams l i which formspaces 4 for the purpose of receiving the ice cans 12 and guidingthe'latter to their properv posiinto which are secured in anysuitablemanner, as by means of the ordinary screw threads,-the upwardlyextending brine circulating tubes 18.L These tubes preferably VSpecification of Letters Patent.

have their upper ends closed and a tight joint is made at their lowerend by means of nuts 19 and suitable gaskets 20.

A dome-shapedshoe 21 having-an extension 22 on its upper side is securedwithin each of the tubes 18 by being screwed or driven into the same,and has extending vertically therethrough an opening, in which issecured the tube 23. The tubes 23 are concentrically arranged within-thetubes 18 and have their upper ends open, the lower ends of these tubesbeing in communication with 'the under side of the shbe 21.

The conduit 11 is provided with outlets 24 in its top, these outletsregistering with the brine circulating tubes 18. The brinecirculatesfrom the conduits 11 upwardly through the outlets 24 and the tubes 23and downwardly through the annular space between the tubes 18 and 23 tothe space below the bottom plate 16, suitable grooves 26 being providedin the extension 22 of the shoe 21 for thepurpose of permitting thebrine to escape. From Fig. 2'it will beobserved that the sides of thecan extend beyond the sides of the conduits 11 so that ample space isfrom under the plate 16-.

For the purpose of providing a tight joint between the lower face of theshoes 21 and the top of the conduits 11 any suitable packing 'means maybe provided and for this purpose I have shown in Fig. 3 annular gaskets'27 surrounding the 'outlets 2 1, these gaskets being preferably securedto the top of the conduit. Instead of this construction that shown inFig. 5 may be used, in which the shoe 21 has an annular groove in itslower face, and a suitable gasket 28 is secured in this groove.

From the foregoing description it will be obvious that since the cansare guided by the beams 14when being placed in position thebrinecirculating tubes of the cans will always register with the conduitoutlets 24, and since the tubes 18 and 23 are both carried by ,thew anthere is practically .no liability of damaging the tubes in handling theSince the weight of each. can is carbe formed between the shoe and thetop of the conduit and prevent any material amount of leakage from thespace under the shoe directly to the space below the bottom of the can.

' 5 having a plurality of brine circulating tubes and means supportingthe can on said con- It will be obvious that various changes maybe madein the minor details of construction, within the scope of the appendedclaims, and therefore I do not-wish to be limited to the exact detailsshown and 'described. I

Having thus described the invention what is claimed as new is:

p 1. In an apparatus for making ice, the combination of a freezing tank,a brine conduit, at the bottom of the tank, having an a outlet in itstop, an ice can supported on said conduit and provided with a brinecirculat-, \ing tube extending upwardly from its botom and communicatingthrough the bottom with the interior of the tank, a second tube securedto said can and arranged within the first tube, and means connectingsaid second tube and said conduit outlet.

2. In an apparatus for making ice, the combination of a freezing tank, abrine conduit, at the bottpm of the tank, having a r plurality ofoutlets in its top, an ice can arranged in the tank above said conduitand extending upwardly from the bottom and communicating through thebottom with the interior of the tank, tubes secured to the can andarranged within said circulating tubes,

duit and establishing communication between said conduit outlets andsaid second- I mentioned tubes.

3. In apparatus for making ice, the com- 5 bination of a freezing tank,a brine conduit, at the bottom of the tank, having an outlet in its top,an ice can arranged in the tank above said conduit and having a brine\circulating tube secured in an opening through 40 the bottom of the canand extending upwardly therefrom,a member secured to the bottom of thecan and covering the outlet in said conduit, said member havin an in-1,o74,417 L c terior opening in communication" with said outlet, a tubearranged within said circulatmg tube and secured in said member andadapted to convey brine from said conduit outlet to the upper part ofsaid circulating tube, and means for conveying brine from the lower partof said circulating tube to the exterior of said can.

4. In apparatus for making ice, an ice can having sheet metal sides anda cast metal' bottom 'plate,said bottom plate having an openingtherethrough, a brine circulating tube closed at its upper end andhaving its lower end secured in said opening, a hollow plug secured inthe lower end of said tube and provided with an openihg or grooveadapted to convey brine from the tube to the space below said-bottomplate, and a tube secured in-said plug and arranged within saidfirst-mentioned tube. v

5. In apparatus for malcin ice, a tank having a brine conduit at the fottom thereof, said conduit being provided" with an outlet in. its top,an ice can arranged in said tank above said conduit and havingan'opening through the bottom thereof in registration with said conduitoutlet, a brine circu-, lating tube secured in said opening andextending upwardl therefrom, a member secured to the bottom of said cansurrounding said conduit outlet,, packin' means between said member andsaid con uit, and a tube arranged within said first-mentioned tubeandsecured to saidmember,

In testimony whereof I afi-X in presence of two witnesses.
